Unbelief

Today I was reading about Zechariah and Elizabeth.  I was really struck by the fact that the angel Gabriel shut Zechariah's mouth as he questioned what was going to happen.  As I reflected on this I thought about this:  did God not want his unbelief to spread before John the Baptist and the Savior were born?  I do not know but it did cause me to wonder how my unbelief at times can effect others and that when I doubt or fear I need to trust God.  I can tend to want all the details revealed just like wondering why God did this yet there are times I must simply trust that He is in control.
